With Veritas, you want to make sure hardware compression is enabled and play with the buffer and block sizes a bit under the device options. I think the default is 32K.

Hello, Veritas 9 - were using version 8 and getting the same problem. Exchange 5.5, NT4 SP6a We can not seem to get better then 100 MB / minute backing up the Exchange servers. using the Exchange agent. Many nights lately it is much worse. The NICs and ports on the switch have all be set to 100/full. IS Maintenance is from 4am - 7am. Ensured that Trend Server Protect is not doing any scheduled scans and that realtime scans exclude Exchange directories. The databases on the 2 servers are not big: One is 25 GBs with 7 GBs of whitespace The other is 17 GBs and only a 300 MBs of whitespace. Nightly oneline defrags are successful. Veritas tech notes point to a fragmented database - I don't buy that unless Exchange IS maintenance is not functioning on both servers. I also have a few other admins that swear by offline defrags - because they always seemed to help. Any ideas where I should be looking?
